The ADUC7060 looks Great! ..if only I knew how to program ARMs...  :(
Dave, can you take some pictures of the analog frontend boards of your most expensive multimeters? Only board layout can be copyrighted, schematics can't, so if we can get a ready to go schematics we can design a slightly different board and have a product as good as the cool guys, for the price of bare components.
I was curious about the implementation of the auto-range too, tonight I thought about it a lot and I had some ideas so I'd like to see if I got it rigt in my mind.

I hope the end product will be so cool and modular and cost effective that the target audience will be ANYONE. I suggest a vibration function in the continuity mode, so we can really fulfill GeekGirl's fantasies!  ;D (Sorry, couldn't resist.)

That would explain the request for a purple case. Well, partly  ;)

I think that we should try to do some type of modular design....

I dont know if we wanna go the Arduino route, those things are so expensive for what you get. Since we will most definitely be making PCBs for modular boards and things like that, making a Main board with a ~$5 PIC Chip seems like a better option to me then having to make the Main board and the have a 30 dollar Arduino attached to it anyway. Unless you are saying that we should just use a Arduino compatible chip on our board and use the Arduino bootloader and IDE to write our code.  .....

Yap,  I agree.
I don't like the Arduino, BasicATOM, BasicX, BASIC Stamp... They cost to much for what you get.

I like the wireless display module, idea. As an option.

The "Service Manual" sometimes has the schematics.  They cost less then $20, some are free.

If you went PIC then you'd need a good reason the stray from the free Microchip C compiler.

I must confess I've never actually tried Microchip's own compiler.  The simple reason being, they don't support (or at least they didn't) the 16F range of devices.  While I was learning C, these were the devices I was playing with, so I had to find a compiler that worked with them.  That's how I got on to PICC.

Once you're used to a compiler, you don't really want to have to swap to a different one (at least, not just for the sake of it anyway).  Hence I never got around to trying Microchip's own compiler.

That is probably due to that anything less than 18F is not C-friendly, as there is no RAM or stack in the usual sense. Stack is very essential thing for a typical C compiler as the arguments for a function are usually pushed on the stack and function local variables also reside there. That makes a 16F a very hostile environment for a C-compiler. Instead there is a big bunch of registers.
